ZDRVHE(3)

💖 NAME 💖

Okay bestie, welcome to the ZDRVHE(3) page from the Library Functions Manual ✨. The file this page is about is literally this exact path, no cap:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/zdrvhe.f

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

The short-and-slay version is right here:

       subroutine ZDRVHE (dotype, nn, nval, nrhs, thresh, tsterr, nmax, a,
           afac, ainv, b, x, xact, work, rwork, iwork, nout)
           ZDRVHE

🦋 Function/Subroutine Documentation 🦋

Full signature with every type and dimension, copied character for character because we do not play about details:

   subroutine ZDRVHE (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nrhs, double precision thresh, logical
       tsterr, integer nmax, complex*16, dimension( * ) a, complex*16,
       dimension( * ) afac, complex*16, dimension( * ) ainv, complex*16,
       dimension( * ) b, complex*16, dimension( * ) x, complex*16, dimension( *
       ) xact, complex*16, dimension( * ) work, double precision, dimension( *
       ) rwork, integer, dimension( * ) iwork, integer nout)
       ZDRVHE

🌸 Purpose 🌸

The purpose block is giving exactly this:

!>
!> ZDRVHE tests the driver routines ZHESV and -SVX.
!>

So yeah, ZDRVHE tests the driver routines ZHESV and -SVX. Periodt. 💅

🎀 Parameters 🎀

Vibe check: here’s the parameter tea ☕, with all the details kept intact, fr fr:

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). The matrix types to be used for testing. Matrices of type j (for 1 <= j <= NTYPES) are used for testing if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used.
• NN — NN is INTEGER. The number of values of N contained in the vector NVAL.
• NVAL — NVAL is INTEGER array, dimension (NN). The values of the matrix dimension N.
• NRHS — NRHS is INTEGER. The number of right hand side vectors to be generated for each linear system.
• THRESH — THRESH is DOUBLE PRECISION. The threshold value for the test ratios. A result is included in the output file if RESULT >= THRESH. To have every test ratio printed, use THRESH = 0.
• TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested.
• NMAX — NMAX is INTEGER. The maximum value permitted for N, used in dimensioning the work arrays.
• A — A is COMPLEX*16 array, dimension (NMAX*NMAX).
• AFAC — AFAC is COMPLEX*16 array, dimension (NMAX*NMAX).
• AINV — AINV is COMPLEX*16 array, dimension (NMAX*NMAX).
• B — B is COMPLEX*16 array, dimension (NMAX*NRHS).
• X — X is COMPLEX*16 array, dimension (NMAX*NRHS).
• XACT — XACT is COMPLEX*16 array, dimension (NMAX*NRHS).
• WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(2,NRHS)).
• RWORK — RWORK is DOUBLE PRECISION array, dimension (NMAX+2*NRHS).
• IWORK — IWORK is INTEGER array, dimension (NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.
